Robin,
thank you for the quick reply. Indeed, but this would still involve to swap parameters around between fixed and non-fixed and changing the lambda function manually rather then just switching the fissint on and off with a single variable.
But no doubt, a wrapper can be done.
I couldn't think of a way to squeeze it into a lamdba single statement, but something like this would do: def fit_function(x, fit, y): p0 = zeros(fit.size) p0[fit] = x p0[~fit] = y where fit is a boolean array, x is the ones to optimised and y are the fixed values. You have the extra overhead of the p0 array allocation for every iteration of the function - but perhaps that is worth it for the convenience. Robin
